WebJan 1, 2024 · We propose a novel multi-modality graph neural network (MAGNN) to learn the lead-lag effects for financial time series forecasting, which preserves informative market information as inputs, including historical prices, raw news text and relations in KG. To our best knowledge, this is the first study to explore the lead-lag effects by embedding ... WebMar 3, 2024 · Graph neural networks take as input a graph with node and edge features and compute a function that depends both on the features and the graph structure. Message-passing type GNNs (also called MPNN [3]) operate by propagating the features on the graph by exchanging information between adjacent nodes.

WebWe propose a novel class of graph neural networks based on the discretised Beltrami flow, a non-Euclidean diffusion PDE. In our model, node features are supplemented with positional encodings derived from the graph topology and jointly evolved by the Beltrami flow, producing simultaneously continuous feature learning and topology evolution. solight dm80WebSpecifically, we use two widely used and open-source GNN algorithms, namely Temporal Graph Convolutional Network (TGCN) and Diffusion Convolutional Recurrent Neural Network (DCRNN), and real-time traffic data from the Greek open-data portal to create models that accurately forecast traffic flow. small bag of chips priceWebWe propose GRAph Neural Diffusion with a source term (GRAND++) for graph deep learning with a limited number of labeled nodes, i.e., low-labeling rate.
